To create a connection, call the class using these arguments: host, user, passwd, acct, timeout, source_address, encoding The first four arguments are all strings, and have default value ''. The parameter ´timeout´ must be numeric and defaults to None if not passed, meaning that no timeout will be set on any ftp socket(s). If a timeout is passed, then this is now the default timeout for all ftp socket operations for this instance. The last parameter is the encoding of filenames, which defaults to utf-8. Then use self.connect() with optional host and port argument. To download a file, use ftp.retrlines('RETR ' + filename), or ftp.retrbinary() with slightly different arguments. To upload a file, use ftp.storlines() or ftp.storbinary(), which have an open file as argument (see their definitions below for details). The download/upload functions first issue appropriate TYPE and PORT or PASV commands. rNTFutf-8encodingcCs6||_||_||_|r2|||r2||||dS)zInitialization method (called by class instantiation).

If the transfer is active, send a port command and the transfer command, and accept the connection. If the server is passive, send a pasv command, connect to it, and start the transfer command. Either way, return the socket for the connection and the expected size of the transfer. The expected size may be None if it could not be determined. Optional `rest' argument can be a string that is sent as the argument to a REST command. This is essentially a server marker used to tell the server to skip over any data up to the given marker.
